Wigan Warriors have invested wisely in new signing Willie Isa according to Bobbie Goulding.

He has seen Isa shine for the Widnes Vikings and feels Wigan are onto a winner with the powerful Samoan international.

Goulding told MEN Sport: ‘‘This is a terrific signing for Wigan because Isa is quality.

‘‘I would not like to come up against him in a dark alleyway because he is one hard man who can look after himself.

‘‘A very tough, talented player and I am very surprised Widnes are letting a player of his class go.

‘‘He is a good professional and it is going to strengthen the Wigan squad in my view.

‘‘Isa is strong and would boost any side. Wigan have got one very good player.

‘‘I also feel they are on the way to the Grand Final this season. I picked Wigan out at the start of the year and I am sure they will be too strong for Huddersfield in the semi-final especially at home.

‘‘You do not bet against Wigan in these type of games and especially with a place in the Grand Final up for grabs. I see Wigan having the edge on Huddersfield who are a good side but this one is at Wigan.’’

Former GB scrum half Goulding is expecting Wigan under Shaun Wane's stewardship to progress and take on Leeds at Odd Trafford in the Grand Final.

He adds: ‘‘I see Leeds beating Saints by four points. The outcome of this one could have been different had it been at Saints but you have to fancy Leeds especially at Headingley.

‘‘They seem to have put their recent dip in form behind them and showed character to defeat Huddersfield and win the League Leaders’ Shield.

‘‘This will have helped them. I just see Leeds having a slight edge because of home advantage.’’

Meanwhile, Salford are strongly linked with the Huddersfield forward Craig Kopczak for next season. Warrington’s Gareth O’ Brien is another likely target along with overseas stars Ben Murdoch Masila and Robert Lui.

Joel Monaghan, Mark Flanagan and Justin Carney have also been discussed.

There is also talk of a new role for Martin Vickers who has already overseen and implemented a wide variety new structures and corporate activities to the Red Devils set up.
